From 28f6d99bff745c2478894e7cecf307f2133af6d7 Mon Sep 17 00:00:00 2001 From: jedarden Date: Wed, 22 Apr 2026 13:57:42 -0400 Subject: [PATCH] =?UTF-8?q?feat(replay):=20smooth=20400ms=20cross-fade=20b?= =?UTF-8?q?etween=20view=20modes=20per=20=C2=A716.11?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement double-buffered canvas cross-fade when switching between dots, Voronoi territory, and influence gradient views. Old layer fades out while new layer fades in with ease-in-out cubic easing over 400ms. Respects prefers-reduced-motion by snapping instantly when set.
